How many match, without building the documents.
The day an entry falls on, in the catalogue's zone. A date-only value ignores the zone.
The first and last day any document falls on, or null when none is dated.
The most recent DATED document, or null. Undated documents sort last and are never "latest".
One row per document name in scope, commonest first.
The documents matching a filter, oldest first. An empty result is an answer, not a failure.
One row per type, largest first.
A patient's documents, queryable. Owns the entries, renders nothing. See
../README.md.
